تفاصيل المنتج

Asphalt Bent Beam Rheometer (BBR)Suitable for determining the low-temperature bending creep stiffness of asphaltS（t）And creep slopemValue can be used to evaluate the low-temperature fracture characteristics of asphalt binders. This instrument is suitable for original asphalt, pressure aged asphalt, and aged asphalt after film oven (or rotary film oven).

1Asphalt Bent Beam Rheometer (BBR)Main technical features and functions

1. The instrument control unit adopts an industrial tablet computer, which displays deformation curves, pressure curves, and temperature curves in real time. The instrument clock software can be set and adjusted.

2. AdoptingPELTIETechnology and refrigeration combined mode, fast cooling speed,40It can be reduced from room temperature to room temperature in minutes-18℃, high temperature control accuracy.

3. Adopting linear differential displacement sensor（LVDT）Equipped with a standard calibration module, displacement parameters can be calibrated accurately and with high precision.

4. Adopting a high-precision, low-noise, and split refrigeration unit, and connecting it to the main unit with a hose to prevent its vibration from affecting the test results.

5. Adopting high-precision load sensors and equipped with standard pressure calibration devices, the pressure can be calibrated accurately and reliably.

6. The host liquid bath is equipped with a magnetic stirrer with adjustable speed, ensuring accurate and uniform temperature of the liquid bath.

7. The air source pressure, pre pressure, load pressure, and air bearing pressure can all be visually displayed in the operating software for easy viewing.

8. Design hasUSBCommunication port, capable of exporting instrument detection data.

9. It has functions such as instrument overload protection and fault warning. When an abnormality occurs, the buzzer will sound an alarm and the interface fault code will be displayed simultaneously.

10. The test time can be set for easy verification240sThe deformation situation after (default)240s）.

11. The time required for calculating the results can be set by software (default)8s,15s,30s,60s,120s,240s）.

12. Adopting two-stage high-precision air filters to provide high-quality compressed air for the air suspension system, ensuring detection accuracy.
